我有一块由 Linux 内核驱动的板。该板为 aarch64/armv8 架构。该板没有apt-get，但有easy_install。我尝试使用 easy_install 进行安装，但出现以下错误，
root@armboard:~# easy3_install pip

来自 /usr/lib/python3.5/site-packages 的 setuptools 36.2.7 (Python 3.5)
请建议在此平台上安装 pip 的方法。
如果可以使用easy_install，我应该遵循哪些步骤来解决此错误？
如果不是，我应该为这个架构获得交叉编译的 pip 二进制文件，还是有任何 Yocto 版本可用？
